We played 'The Crystal Maze' to tell you everything you need to know about the show's return to British TV

"The Crystal Maze" will return for a one-off special later this month after a 21-year hiatus from British television.

The cult entertainment show was a fixture on Channel 4 between 1990 and 1995, and there remains enormous affection for the programme.

So much so that a special visitor attraction has been open in London since March, which enables members of the public to live the programme for real. Business Insider paid a visit earlier this year and it was so faithful to the original show, it is little wonder Channel 4 is using it as the set for its one-off special.

Originally hosted by the flamboyant Richard O'Brien, "The Crystal Maze" featured a team of contestants circulating themed zones in a purpose-built maze, completing physical and mental challenges to win crystals.

Channel 4 released a teaser trailer for the programme's comeback last week. It features the original 1990s theme tune and O'Brien shouting: "Let the fans blow." This is reference to the famous crystal dome, where contestants turn their crystals into prizes by snatching gold tickets from the air in a wind-filled box.
